Totally Light Controlled Thyristor-Optically Triggerable and Optically Quenchable Static Induction Photo-Thyristor

Optically Triggerable and optically quenchable Static Induction Photo-Thyristor (SIP Thy) is described in this paper concentrating on the optical direct/indirect Triggering and optical quenching mechanisms. Using only two LEDs drived by CMOS logic IC, 300V-2A is directly triggered and quenched in a turn-on time of 6.2psec and a turn-off time of 15psec, and 540V-lA is indirectly switched in a turn-on time of 545nsec and a turn-off time of 7.lSpsec, until now.
